Abstract
- Trichoblastoma is a rare, benign skin tumor of adnexal origin that differentiates toward the hair germ, the embryonic precursor of a hair follicle. Clinically, it presents as a slow growing, solitary, well-circumscribed nodule located predominantly in the head and neck area, with a predilection for the scalp. The trunk, proximal extremities and perianal and genital regions may also be affected. We herein present a case of trichoblastoma which occurred on the trunk as a solitary subcutaneous mass with a central tiny pore in 53-year-old man.
